Description

2525th

Die Erfindung betrifft ein Verfahren zum Herstellen von ringförmigen Dichtungen mit relativ großem Durchmesser aus elastomerem Material nach dem Gattungsbegriff des Patentanspruchs.The invention relates to a method for producing annular seals with a relatively large size Diameter made of elastomeric material according to the preamble of the claim.

Ein derartiges Verfahren ist aus der DE-OS 30 12 387 bekannt. Zum Verbinden der Enden von strang- oder streifenförmigen Gummiartikeln miteinander wird nach dem bekannten Verfahren zwischen die Enden zweier vulkanisierter Dichtungsstreifen eine die Stirnflächen der Streifen mit Übermaß überdeckende Scheibe vulkanisierbaren Dichtungswerkstoffes eingelegt und unter Herstellung einer Haftverbindung nach beiden Seiten vulkanisiert.Such a method is known from DE-OS 30 12 387. For connecting the ends of strand or strip-shaped rubber articles with each other is according to the known method between the ends of two vulcanized sealing strip a disc that overlaps the end faces of the strips with an excess vulcanizable sealing material inserted and producing an adhesive connection after both Vulcanized sides.

Bei einem solchen Verfahren wird auf den Einsatz eines Versteifungsringes verzichtet. Die Armierung eines Dichtungsringes mit einem Versteifungsring hat aber den Vorteil, daß der zum Beispiel bei Rohren zum Einsatz kommende Dichtungsring beim Einführen eines Rohrendes in die Muffe eines damit zu verbindenden Rohres nicht in unkontrollierbarer Weise in die Muffe hineingedrückt wird, wie es bei einem nicht armierten Dichtungsring der Fall sein kann. Nach dem Einführen des Rohrendes in die Muffe besteht dann aber keine Sicherheit, daß der Dichtungsring die vorgesehene Abdichtungsposition innerhalb des Ringspaltes zwischen der Muffe und dem eingesteckten Rohrende eingenommen hatWith such a method, the use of a stiffening ring is dispensed with. The reinforcement a sealing ring with a stiffening ring but has the advantage that, for example, in pipes for Use of the upcoming sealing ring when inserting a pipe end into the socket of one to be connected to it Pipe is not pressed into the socket in an uncontrollable manner, as it is with a non-reinforced Sealing ring may be the case. After the pipe end has been inserted into the socket, there is none Security that the sealing ring the intended sealing position within the annular gap between the socket and the inserted pipe end

Aus der NL-OS 77 04 936 ist auch bereits ein Verfahren zur Herstellung eines Dichtungsringes mit einem Versteifungsring bekannt. Dabei wird der Versteifungsring innerhalb einer Matrize angeordnet, die anschließend mit einem elastomeren Material gefüllt wird. Dieses Verfahren eignet sich aber nur für die Massenherstellung verhältnismäßig kleiner Dichtungsringe. Bei großen Dichtungsringen, beispielsweise solchen mit einem Durchmesser von mehr als 1 m, oder bei der Einzelfertigung der Dichtungsringe beeinflussen die Kosten zur Herstellung einer Matrize die Produktionskosten der Dichtungsringe so sehr, daß die Matrizenfertigung wirtschaftlich unrentabel istFrom NL-OS 77 04 936 a method for the production of a sealing ring is already available known a stiffening ring. The stiffening ring is arranged within a die, which is then filled with an elastomeric material. This procedure is only suitable for Mass production of relatively small sealing rings. For large sealing rings, for example those with a diameter of more than 1 m, or In the case of individual production of the sealing rings, the costs of producing a die influence the production costs the sealing rings so much that the die production is economically unprofitable

Der Erfindung liegt die Aufgabe zugrunde, zu einem Verfahren zu gelangen, mit dem sich ohne Anwendung von aufwendigen Matrizen ein mit einem Versteifungsring armierter Dichtungsring herstellen läßt. The invention is based on the object of arriving at a method that can be used without application A sealing ring reinforced with a stiffening ring can be produced from complex dies.

Ausgehend von dem eingangs beschriebenen Verfahren wird zur Lösung der gestellten Aufgabe vorgeschlagen, daß eine der Länge des abgetrennten extrudierten Profils entsprechende Länge Draht mit einem Querschnitt, der dem Querschnitt des Hohlraumes im extrudierten Profil entspricht, abgetrennt und ringförmig gebogen wird und daß der von dem extrudierten Profil abgetrennte Teil auf den gebogenen Draht aufgeschoben wird, worauf die Enden des Drahtes verschweißt werden.Based on the method described at the beginning, it is proposed to solve the problem posed, that a length of wire corresponding to the length of the severed extruded profile with a cross-section, which corresponds to the cross section of the cavity in the extruded profile, separated and annular is bent and that the part cut off from the extruded profile is placed on the bent wire is pushed, whereupon the ends of the wire are welded.

im Gegensatz zu den bekannten Rollringausführungen ermöglicht das erfindungsgemäße Verfahren die Herstellung eines Dichtungsringes bei freier Wahl des Ringquerschnittes, so daß diesem die Form gegeben werden kann, welche die zuverlässigste Abdichtung gewährleistet und verhindert, daß beim Einführen eines Rohrendes in die Muffe der Dichtungsring unkontrolliert in den Ringraum hineingeschleppt wird. Bei einem nach dem erfindungsgemäßen Verfahren hergestellten Dichtungsring ist der Versteifungsring völlig in das elastomere Material eingebettet und von der Umgebung abgeschlossen, so daß auch bei Verwendung eines an sich korrodierenden Materials als Versteifungsring dieser Ring nicht dem korrodierenden Einfluß der Umgebung ausgesetzt ist.In contrast to the known rolling ring designs, the method according to the invention enables Production of a sealing ring with free choice of the ring cross-section, so that this is given the shape which ensures the most reliable seal and prevents that when inserting a The end of the pipe is dragged into the socket of the sealing ring in an uncontrolled manner into the annulus. At a The sealing ring produced by the method according to the invention is completely inserted into the stiffening ring elastomeric material embedded and closed off from the environment, so that even when using a in itself corrosive material as a stiffening ring, this ring does not have the corrosive influence of the Environment is exposed.

Als Material für den Versteifungsring wird vorzugsweise verzinkter Stahl verwendet, obwohl auch andere Metalle oder ein verhältnismäßig steifer Kunststoff besonders geeignet sein können. In der Regel wird als Material für den Versteifungsring Stahldraht mit einem rechteckigen oder quadratischen Querschnitt in Betracht kommen.The material used for the stiffening ring is preferably galvanized steel, although others are also used Metals or a relatively stiff plastic can be particularly suitable. Usually as a Material for the stiffening ring is steel wire with a rectangular or square cross-section come.

Vor dem Aneinanderschweißen der Enden des zu einem Kreis gebogenen Drahtes werden die Enden des zuvor aufgeschobenen Profils durch eine Stauchung des elastomeren Materials so weit zurückgeschoben, daß die Drahtenden für den Schweißvorgang frei zugänglich sind, und das Schweißen ohne Verbrennungs- oder Schmelzgefahr für das elastomere Material erfolgen kann. Nach dem Schweißvorgang und dem Abkühlen der Schweißverbindung werden die äußeren Enden des Profils zusammengefügt und durch Kleben oder Vulkanisieren miteinander verbunden.Before welding the ends of the wire bent into a circle, the ends of the previously pushed profile pushed back so far by compression of the elastomeric material that the wire ends are freely accessible for the welding process, and the welding without burning or Melting hazard for the elastomeric material can occur. After welding and cooling the welded connection, the outer ends of the profile are joined together and by gluing or Vulcanizing linked together.

Vorzugsweise wird für den Dichtungsring ein Profil extrudiert, das mit einem Flansch versehen ist, der im eingebauten Zustand gegen die Kopffläche der Muffe anliegt, wobei der Hohlraum zur Aufnahme des Versteifungsringes im Flanschbereich vorgesehen ist. Durch diese Anordnung wird ein Hineinschleppen des Dichtungsringes beim Einschieben eines Rohrendes in die Muffe mit Sicherheit ausgeschlossen.Preferably, a profile is extruded for the sealing ring, which is provided with a flange in the installed state against the head surface of the sleeve, the cavity for receiving the Stiffening ring is provided in the flange area. This arrangement prevents the Sealing ring when pushing a pipe end into the socket is definitely excluded.

Der nach dem erfindungsgemäßen Verfahren hergestellte Dichtungsring kann vorzugsweise bei Verbindungen von Rohren eingesetzt werden, die aus Beton, Ton, Gres, Steinzeug, Asbestzement usw. bestehen, und einen Durchmesser von 1—2 m oder mehr aufweisen. Erfindungsgemäß hergestellte Dichtungsringe lassen sich aber auch bei Kunststoffrohren mit kleineren Durchmessern verwenden. Dichtungsringe lassen sich nach dem erfindungsgemäßen Verfahren immer dann besonders vorteilhaft herstellen, wenn nur eine geringe Anzahl von Dichtungsringen benötigt wird und die Investition für eine Matrize aufgrund der geringen Anzahl nicht oder nur schwierig amortisierbar ist.The sealing ring produced by the method according to the invention can preferably be used for connections of pipes made of concrete, clay, gres, stoneware, asbestos cement, etc., and one Have a diameter of 1–2 m or more. Let sealing rings produced according to the invention but can also be used for plastic pipes with smaller diameters. Sealing rings can according to the method according to the invention always produce particularly advantageous if only a small one Number of sealing rings is required and the investment for a die due to the low Number is difficult or impossible to amortize.

Ein elastomeres Material, z. B. Gummi, wird zu einem Profil extrudiert, das aus einem im wesentlichen rechteckigen Teil 1 besteht, der einserseits mit einer Lippe 2, mit einem hammerkopfförmigen Ende 3 und andererseits mit einem Kragen 4 versehen ist. In dem Kragen 4 ist ein Hohlraum 5 von quadratischem Querschnitt vorgesehen, der sich in Extrusionsrichtung über die Profillänge erstreckt. Der untere Bereich der rechteckigen Teils 1 ist an der Außen- und Innenoberfläche mit Rillen 6 bzw. 7 versehen.An elastomeric material, e.g. B. rubber, is extruded into a profile consisting essentially of a Rectangular part 1 consists of one side with a lip 2, with a hammer head-shaped end 3 and on the other hand is provided with a collar 4. In the collar 4 is a cavity 5 of square Cross-section provided which extends in the extrusion direction over the length of the profile. The lower area of the rectangular part 1 is provided with grooves 6 and 7, respectively, on the outer and inner surfaces.

Vom extrudierten Profil wird eine Länge abgetrennt, die dem Umfang des herzustellenden Dichtungsringes entspricht, während eine entsprechende Länge eines verzinkten Stahldrahtes 8 mit einem Querschnitt, der in den Hohlraum 5 paßt, ebenfalls abgetrennt wird. Der abgetrennte Stahldraht 8 wird auf einer Rollenbank zu einem Kreis gebogen.A length is cut from the extruded profile which corresponds to the circumference of the sealing ring to be produced corresponds, while a corresponding length of a galvanized steel wire 8 with a cross-section that in the cavity 5 fits, is also separated. The severed steel wire 8 is on a roller bench curved in a circle.

Der vom Profil abgetrennte Teil wird auf den kreisförmig gebogenen Draht geschoben, worauf die äußeren Enden soweit zurückgedrückt werden, daß die Enden des Drahtes 8 freiliegen und aneinandergeschweißt werden können, worauf das elastomere Profil ίο wieder zurückgeschoben wird, bis die Enden einander berühren. Die Enden werden dann aneinander geklebt oder vulkanisiert.The part separated from the profile is pushed onto the circularly bent wire, whereupon the outer ends are pushed back so far that the ends of the wire 8 are exposed and welded together can be, whereupon the elastomer profile ίο is pushed back again until the ends meet touch. The ends are then glued or vulcanized together.

Nachdem der Dichtungsring auf diese Weise hergestellt ist, bildet der Kragen 4 einen nach außen gerichteten Flansch 4', der nach dem Einbringen eines Rohres 11 in die Muffe 9 eines Rohres 10 gegen die Stirnseite der Muffe anstößt. Der Versteifungsring 8 innerhalb des Flansches 4' verhindert, daß beim Einschieben des Rohres 11 in die Muffe 9 der Dichtungsring mitgeschleppt wird. Die Lippe 2 mit dem hammerkopfförmigen Ende 3 liegt dichtend auf dem Ende des Rohres 11 an der Außenoberfläche an.After the sealing ring is made in this way, the collar 4 forms an outwardly directed flange 4 ', which after the introduction of a pipe 11 in the socket 9 of a pipe 10 against the Front side of the sleeve abuts. The stiffening ring 8 within the flange 4 'prevents the Pushing the tube 11 into the sleeve 9 of the sealing ring is dragged along. The lip 2 with the hammer head-shaped end 3 is sealingly on the end of the tube 11 on the outer surface.
